What is site-to-site VPN?
A site-to-site virtual private network (VPN) refers to a connection set up between multiple networks. This could be a corporate network where multiple offices work in conjunction with each other or a branch office network with a central office and multiple branch locations.
What is SSL VPN?
SSL VPN allows users from any Internet-enabled location to launch a web browser to establish remote-access VPN connections, thus promising productivity enhancements and improved availability, as well as further IT cost reduction for VPN client software and support. Additional VPN background information is widely available.
What is VPN security?
VPN security is only as strong as the methods used to authenticate the users (and the devices) at the remote end of the VPN connection.
Does SSL VPN have antivirus?
However, public machines used for SSL VPN may not have the required antivirus software installed and properly maintained; also, they typically do not have a host-based firewall installed and enabled.
Does SSL VPN require additional software?
If application access requirements are modest, SSL VPN does not require additional client software to be installed on the endpoint device. For broader application access, a dynamically downloadable tunneling client is typically delivered when needed to the client machine to support such full SSL VPN capabilities.
Is SSL VPN blocked?
In most environments, outbound Secure HTTP (HTTPS) traffic, which is also based on SSL, is not blocked. This means that even if a particular local environment does not permit outbound IPSec VPN sessions (such restriction is not unusual), SSL VPN is likely free of such restriction.
Is SSL VPN clientless?
As a result, SSL VPN is also known as “clientless VPN” or “ Web VPN.”. Another SSL VPN advantage over IPSec VPN is its ease of use for end users. Different IPSec VPN vendors may have different implementation and configuration requirements. SSL VPN, on the other hand, requires only a modern web browser.
Why use a VPN?
There are many reasons for such overwhelming adoption and business success; two major factors are total ownership cost savings and productivity enhancements. The total ownership cost can be considered as the initial deployment cost plus the cost of user training, support, and facility maintenance over time. Productivity enhancements can be measured in terms of tool effectiveness, user time savings, usability improvements, and user satisfaction.
What is an SSL VPN (Secure Sockets Layer virtual private network)?
An SSL VPN is a type of virtual private network ( VPN) that uses the Secure Sockets Layer ( SSL) protocol -- or, more often, its successor, the Transport Layer Security ( TLS) protocol -- in standard web browsers to provide secure, remote access VPN capability.
How SSL VPNs work
SSL VPNs rely on the TLS protocol, which has replaced the older SSL protocol, to secure remote access. SSL VPNs enable authenticated users to establish secure connections to internal HTTP and HTTPS services via standard web browsers or client applications that enable direct access to networks.
Advantages of SSL VPNs
One of the primary advantages of an SSL VPN is that it uses the TLS technology implemented in modern web browsers, so there is no need to install specific client software. That makes it easy to deploy. In addition, the encrypted circuits created using TLS provide much more sophisticated outbound connection security than traditional VPN protocols.
Security risks of SSL VPNs
Despite the benefits an SSL VPN provides, security risks are also associated with the technology. Notwithstanding its enhanced security measures, an SSL network can be susceptible to spreading malware, including spyware, worms, viruses and Trojan horse programs.
IPsec VPN vs. SSL VPN
Using an SSL VPN can have advantages over using an IPsec VPN. First, IPsec remote access VPN connections require installation of IPsec client software on client systems, which may, in turn, require the purchase and configuration of additional software. SSL VPNs can be set up using existing browsers and minimal configuration modification.
